Every now and then, a
documentary film comes along that makes you sit up and take notice of the world
around you: it makes you realize what a wondrous world we live in, appreciate
the amazing complexity of life, and feel the exhilaration of learning new
things. The Life of Mammals is one of these documentaries, doing for the
world of mammals what Blue Planet: Seas of
Life did for the oceans and Cosmos did for science in general. Written
and narrated by David Attenborough, who is famous for his wildlife programs
including The Living Planet and The Life of Birds, The Life of
Mammals is everything that a documentary should be: fascinating,
compelling, intelligent, and stunningly beautiful.

The series is intensely
interesting from the very first moment. The first episode, "A Winning
Design," explores the question of what is a mammal, and shows how the
mammalian adaptations of warm blood, fur, and milk production help make mammals
of all kinds highly successful. After that solid opening, the series continues
to be extremely well organized, with each episode tightly focused on a
particular group of mammals: insect eaters, meat eaters, water dwellers, tree
dwellers, and so on. The episodes move in the direction of increasing
evolutionary complexity, starting with the mammals that are most similar to the
earliest mammals who shared the Earth with the last of the dinosaurs, and then
showing how mammals adapted themselves to different food sources and habitats.

All of the episodes open up a
window into the natural world to give us a fascinating look at the lives and
behavior of a wide variety of mammals. A total of ten 50-minute episodes make
up the series, starting with "A Winning Design" and moving on to
"Insect Hunters" and "Plant Predators," exploring some of
the earliest adaptations that mammals made as they expanded into new
evolutionary niches after the extinction of the dinosaurs.
"Chisellers" discusses the mammals who have developed special tools
to feed on tough materials like seeds, while "Meat Eaters" takes a
look at what it takes to be a predator of more than just insects, and the title
of "Opportunists" refers to omnivores, creatures whose willingness to
eat whatever comes to hand makes them quite adaptable. The next two episodes
focus on habitat rather than diet: "Return to the Water" examines the
mammals, like seals and dolphins, that returned to the sea, and "Life in the
Trees" shows us what it takes to make a living far above the ground. The
final two episodes move closer to home, encouraging us to examine our place in
the mammal world: "Social Climbers" looks at the complex social
behavior of monkeys and apes, and "Food for Thought" wraps up the
series with a look at one very adaptable and successful mammal: Homo sapiens.

The photography in The Life
of Mammals is nothing short of amazing, on a par with the incredible
footage captured in Blue Planet: Seas of Life. The creators of The
Life of Mammals must have gotten the best of the best to film the animals
documented here. We see even the most reclusive of mammals in their natural
habitat, going about their daily business, revealing the secrets of their
habits as if no one were watching at all. Much of the camera work reveals
extraordinary preparation and foresight, such as when we see a perspective of
an anteater slurping down termites... from the point of view of inside the
termite mound.

I'm used to the
"disembodied voice" style of documentary narrators, as we get, for
instance, in Attenborough's narration of Blue Planet: Seas of Life, so I
was a bit surprised at first to see Attenborough himself in the picture,
speaking directly to the camera and leading us himself to all the different
locations of the series. I quickly saw that this in-person style works very
well in The Life of Mammals, and indeed it makes sense, since this is
very much Attenborough's own project. One of the benefits of Attenborough's
presence in the episode is that he often demonstrates the ways that scientists
have been able to find out so much about the mammals that we see: from tiny
flexible cameras inserted into a burrow to cranes reaching up to the rainforest
canopy, we see the methods as well as the results of scientists' work.

The Life of Mammals is
full of fascinating information, but that is far from the only thing that makes
it great: on top of that, Attenborough's narration ties together all the
information into a logical structure, with everything explained in an extremely
clear and understandable manner. Attenborough always addresses the viewer as an
intelligent partner in discovery: there's none of the condescending tone that
crops up all too often in documentaries that try to "make it easy"
for the viewer.

One mark of a great program is
that you don't notice the time passing as you watch it, and that's certainly
the case here. With every episode, I was completely absorbed into the
fascinating world that Attenborough opened up before me, and when he wrapped up
and the end credits rolled, I was always surprised: is it over already? And
each episode left me hungry to know more, not because there was anything left
unexplained in the episode, but because the subject was so interesting.

The Life of Mammals is
without a doubt a fantastic series for the entire family. It's not written with
children particularly in mind, but in my view that makes it even better:
there's no silliness here of trying to "make learning fun" (which
always carries the subtext that learning really isn't fun, but rather a chore
to be sugar-coated), but rather a wholehearted and contagious enthusiasm for
exploring the wonders of the natural world.

The DVD

The Life of Mammals is
attractively packaged as a four-disc set, with each DVD in its own plastic
keepcase, inside a beautiful glossy paper slipcase.

Video

The Life of Mammals is a
stunningly beautiful program as well as an incredibly rich one. Presented in
its original 1.85:1 widescreen aspect ratio, and anamorphically enhanced, the
image here is clean, clear, and simply gorgeous. Colors are bright and vibrant,
but always natural as well. The image is clear, with fine detail present at all
levels, thanks in no small part to the almost total absence of edge
enhancement. What's even more amazing is that all of the footage looks
fantastic: not just the regular shots of Attenborough talking, or of the
landscape, but even the images of tiny, reclusive mammals whose picture was
captured using special hidden cameras, infrared, or underwater photography. I
don't know how the photographers did it, but it's amazing.

The Life of Mammals also
gets high marks because it uses a variety of image techniques to present
information in the most effective manner possible. In addition to the traditional
camera work (which is impressive enough as it is), we are shown radar pictures,
infrared images, and even computer-generated images at times, all seamlessly
integrated into the program to produce the right effect at the right time. At
no time are special visual effects used just for their own sake: what we get is
a harmonious whole in which the visual element, along with the audio element
and the content of the program, all work together to create a stunning result.

Audio

The Life of Mammals is
an exemplar of "how to use sound well." The Dolby 2.0 soundtrack is
used to present information in ways that couldn't be done with an image or by
explaining it verbally. As just one example, in "Insect Hunters," we
are shown bats who hunt by using sonar, pulses of sound beyond the hearing
range of humans, and their recorded cries are "translated" into
frequencies we can hear, giving us an entrance into the noisy bat world. What's
more, we're then introduced to bats who find their prey not by sonar but by
their incredibly sensitive hearing: the audio track mutes out the background
noise and lets us actually hear a moth flapping its wings, letting us
experience with our own ears the way that the bat hunts.

In addition to this, the sound
quality is also excellent, offering a clear, clean, and always perfectly
understandable audio experience. English subtitles for the deaf and hard of
hearing are also provided.

Extras

The special features here offer
a modest degree of additional value. Each of the four discs has a section of
"fact files" that provides further text information on some of the
mammals presented in the episodes on that disc, and a photo gallery.

The first disc also includes a
ten-minute video of scenes from the series, set to music; it looks a lot like a
giant trailer for the series, but without a voiceover. An isolated musical
score is also provided on this disc, with seven different sections of the score
accessible.

On the third disc, three short
behind-the-scenes featurettes are included: "Platypus" (8 minutes),
"Elephants" (6 minutes), and "Big Cats" (8 minutes). Though
short, these are quite interesting, as they're presented and narrated by
Attenborough just as the main feature is, and offer additional information and
insights into these mammals.

The menus for The Life of
Mammals are very pleasing, with fully skippable preliminary material and
clear, easy-to-navigate screens.

Final thoughts

What can I say? Go buy this
set. The Life of Mammals is a stunning knockout of a documentary, with
writer and narrator David Attenborough taking viewers on a compelling and
fascinating journey through the animal kingdom that we're a part of. Any viewer
who appreciated the Blue
Planet: Seas of Life documentary will absolutely want to see The
Life of Mammals, which is even a bit better than that ground-breaking ocean
documentary. The Life of Mammals gets a well-deserved DVDTalk
Collector's Series rating, so stop reading and go order this set. You'll be
glad you did.
